Three-time champion Jin Young Ko birdied six of her last nine holes Friday for an 8-under 63 and a two-stroke lead over four players in the LPGA Tour’s Founders Cup. Trying to win the event on a fourth venue, Ko had a 12-under 130 total at Bradenton Country Club after her second straight bogey-free round. Yealimi Noh had a 64 to match fellow American American Angel Yin — who shot her second straight bogey-free 66 — and Japan’s Minami Katsu (65) and South Korea’s Jin Hee Im (66) at 10 under.
